that's just the distance between 2 points
the distance between (x1,y1) and (x2,y2) is

D= √((x2-x1)^2+(y2-y1)^2)

we can find the distance between S and Q or P and R

S and Q is (0,0) and (a,b)


D= √((a-0)^2+(b-0)^2)

D= √(a^2+b^2)

distance between P and R is between(0,b) and (a,0)

D= √((a-0)^2+(0-b)^2)

D= √((a)^2+(-b)^2)

D= √(a^2+b^2)


√(a^2+b^2) = √(a^2+b^2)
so the lengths of diagonals are congruent
